Patent number: 11229895Abstract: A chemical reaction method includes preparing a chemical reaction apparatus including a horizontal flow reactor partitioned into multiple chambers by multiple partition plates. A liquid content horizontally flows with an unfilled space provided thereabove. a microwave generator and a waveguide that transmits microwaves to the unfilled space are also included. The reactor is inclined such that, in each of the chambers, a weir height on an inlet side is higher than a weir height on an outlet side by at least an overflow depth at the partition plate on the outlet side. The content is flowed over each of the multiple partition plates inside the reactor. The content flowing inside the reactor is irradiated with microwaves. The inclination angle of the reactor is changed in each of the chambers so that a weir height on an inlet side is higher than a weir height on an outlet side.Type: GrantFiled: October 17, 2019Date of Patent: January 25, 2022Assignee: MICROWAVE CHEMICAL CO., LTD.Inventors: Akinori Ishizuka, Iwao Yoshino, Kunitaka Momota, Yasunori Tsukahara

Publication number: 20090180947Abstract: To recycle fluoride by recovering calcium fluoride having a particle size and purity suitable for production of hydrogen fluoride, from a fluoride-containing effluent or a hydrofluoric acid-containing effluent. This method comprises reacting the fluoride-containing effluent or the hydrofluoric acid-containing effluent with an aqueous calcium chloride solution, under an acidic condition with hydrochloric acid where calcium fluoride has a comparatively high solubility. Calcium fluoride having a high purity and a large particle size can be deposited. The hydrochloric acid residues from the reaction or formed through the reaction is reacted with an inexpensive calcium compound such as calcium hydroxide, calcium oxide and calcium carbonate to produce an aqueous calcium chloride solution, and the aqueous calcium chloride solution is reused for the treatment of the hydrofluoric acid-containing effluent.Type: ApplicationFiled: August 17, 2004Publication date: July 16, 2009Applicant: Morta Chemical Industrial Co., Ltd.Inventors: Kunitaka Momota, Kazumasa Yamamoto, Youichi Inoue, Shuuichi Watanabe
